Application tiled August 19, 1907. Serial No. 389,197.

To all whom it may concern:

. Be it known that I, EDWIN C. iVAsHURN, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Dumping- Cars; and I do hereby declare the followin to be a full, clear, and exact description o the invention, such as will enable others skilled in the art t0 which it appertains to make anduse the saine.

My invention relates to dumping cars and especially to those having boxes or bodies mounted for lateral pivotal movements so as to dump the load at either side of the car.'

The invention is articularly directed to llocking the pivoted box' or body of the car in normal position and for releasin the same, and for moving the sides of suc box or body to and from operative position.

Generally stated, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

' In the accompanyin drawings which illustrate the invention, like characters indicate like parts throu Vhout the several views.

Referring to the rawings, Figure 1 is a plan view of the improved car. Fig. 2 is a side elevation of the saine, with some parts broken away and someparts sectioned. Fig. 3 is an end elevation of the car, with some parts sectioned; and Fig. 4 is anend elevation of the car showing the box or body thereof in a dnmpin sition.

The car truck, whic ma be of any suit. able construction, is re erably provided with flanged wheels a apted to run upon rails (not shown). As illustrated in the drawings, the truck frame is iliade up of side sills 1, center sills or draft sills 2 and cast bolster end sills 3, and the wheels 4 are secured to axles 5 journaled in suitablc'boxes 6 held by brackets 7 rigidly secured to and projecting below thc side sills 1.- The cast bolster end sills 3 are provided with raised centrally located bosses 3 that project be1 tween, are secured to, and serve to space apart the center or draft sills 2. The coll ler draft bai' L is connected t0 the center si s 2 by a suitable draft riggiu b, indicated in outline only in Fi 2. e intermediate` portion of the coup er draft bar a rests di rectly upon the raised boss 3 of the adj? cent sill 3. The cast truck bolster or end sills 3, it will be noted, is provided with laterally projecting reinforcing flanges, or,

iiiotlier words, is angularin cross section, being, as shown, channel-shaped. The box or body 8 of the ca r is pivotal y connected to the center sills 2 by heavy hinge brackets 9 of the box 8 are separable or removable therefrom, and at the upper edges of their end portions they are pivotally connected to the upper members 13 of telescopically extensible le u, the lower sections 14 of which are pivota ly connected at their lower ends to bearings 15 rigidly secured to the ends of .the transoins 3. As shown, the leg sections 14 telescope into the leg sectionsl 13, and the latter work freely between the adjacent ends of the box and guide bars 16 secured to but spaced apart from the ends of said box, as best shown in Fig. 1. tions 413 are connected tothe a( jacent ends of the box 8, refer-ably by short chains 17, the purpose o? clearly appear.

The relative arrangement of the extensible legs, the box and the connections 17 above described is such that when the box stands in a horizontal or normal position, as best shown in FgB, both of the box sides or doors 12 will by gravity be moved into closed posi`4` tions. To positively lock the said sides to the box wheny they are thus brought to their Si closed positions, cooperating lock pins 18 and sockets 19 aie provided, and these, as shown. are secured respectively in the op )osite edges of4 the ends of the box 8 and on die end poi tions of the said sides 12. As clearly shown in Fig. 3, tliese'interlocking parts 1S and l!) are engaged so that they positively lock the sides 12 in closed positions against the sides of the box 8.

To the ends of the box 8 at diagonall opposite sides of the center of the box, apply locking devices, referably in the form of pivotally connecte dogs 20, the laterally bent free ends pf whichy are adapted to be passed through perforations 21 in the ad lucent upper leg ,sections 13` and into ock notches 22 formed in the cooperating The up er leg sec-4 which will hereinafter more f no j ythe box sides or doors 12vare`held againstvertical movements and, hence, locked to the box by the cooperating lock pins 18 and sockets 19. The lock dogs 20 are shown as provided with projecting perforated ears 20u to which trippmg connectlons, such as ropes or wires, (not shown) may be. attached and extended therefrom to convenient position foi tripping at the side of the car. Y

When the loaded box is to be turned into a -lumping position, the two lock dogs 2O Lwst be moved into' released positions so thatv the box is then free to movewith respect tor .the extensible legs. l/Vhen the box is re- ,leased it may, by slight force, beA caused to move" pivotally toward either side of the truck, or if the box be loaded a little heavier on one side' thanthe other it will itself be moved by gravity into a position to dump the load onY that side of the car. ABy reference to Fig. 4 it will be seen that when the box moves into a dumping position the upper leg sections on the rising side of the box are caused to move telescopically on the coperating leg sections, thereby increasing vthe length of these leg sections Without causing the connected box side 12 to move from its closed position. The extensible leg sections on the falling or lowered side of the box not bei capable of shortening up, serve to lift i theno Vso ' the mrlv i be' automatically returned to normal positionv 'in Fig. 4, the *lowered si x side `12 on the lowered. side of the box from normal position and away from the box, so that the load is left free to slide out of the box at one side of the truck. When the box is moved back to its normal position, the dogs 20 automatically rengage with the lock seats in the sections of the cooperating extensible legs, under the action of gravity, so that the box becomes automatic` ally locked upon reaching its normal position. The lifted bx side 12 is held by gravity in an approximately veiticalposition and the connections 17 between the legs and the'box are so arranged'that under lipward movement of the lowered side of the box the sockets 19 on the raised side will be carried into engagement with the coperating lock pins 18 on the box.

[t is important to note that whenthe box orxbody isina dumping ositio1i,-as shown e of said body isrelieved from the weight of the opened door, while the closed door and partsnf the extensible legs are addedte the raised side vsorboxse-that thesaid body would by gr ty as soon as the load is dumped.

All parts of the truck frame areprefdrably constructed of metal. The sides and` 'ends of the box are. also Apreferably constructed -of metal suitably reinforced by angle irons, and the bottom of the said box sides 12 are shown as provided at their ends with flanged reinforcing bars l2, the uppei' end's of which are pivotally connected to the upper ends of the coperating upper leg sections 13 by pins 25. Also in this preapplied to the corners of the box 8.

The structural iron side sills 1 of the car truck are cut away above the Ajiournal-box, as indicated by dotted lines marked 1 on Fig. 2, and are reinforced by flanges? of the brackets or pedestal castings/7. f

By reference to Fig. 3 it=will be noted that the bottom 8 of the car body 8 is located above the lower marginal portions of said box, so that a portion of said box may move belowthe topsl of the wheels, as `shown in Fig. 4, when the box'is in a dumping position. The said car body 8, at its ends, is provided with angleeends sills 8b (see articularly Fi 4. 2) that carry the body, side and interme iate sills 8c on their lower legs or flanges.

A dumping car of the kind described is capable of man uses, but is especially adapted for use m'handling dirt and coal, in which use it will usually be arranged to run upon a track.

What I claim is l. The combinationwith a truck and a box centrally `hinged thereto for lateral dumpin movements, said box4 having displaceab e sides, of extensible legs pivotally connected to the frame of said truck and to said displaceable sides, and means for locking said box to one or more of the sections means for locking said box against movement with respect to said lower legscctions movement with respect to stantially as described.
